Connecting earphones

The SEK checks the headphone's impedance when a headphone is plugged in at switching on, or each time a headphone is newly plugged in.

To connect earphones to the SEK:
  1. Turn down the volume.
    The volume can be altered between -100 dB to +27.5 dB in steps of 0.5 dB.
  2. Insert the cable’s 3.5 mm jack plug into the phones socket on the SEK.

The earphones have been connected.
